In December 1708, Claes married Rensselaerswyck
native Dirkje Barheit at the Albany
Dutch church. By 1724, the marriage had produced
seven children who were christened in the Albany church where, over the
next two decades, both parents were occasional baptism sponsors.

In 1709, his first
ward house was accorded a modest assessment. In 1710,
he was appointed constable. The next year, he was named high constable.
In 1715 and again in 1724, he served as firemaster in the first
ward. In 1720 and in
1742, his name was included
among the freeholders living in the first ward. In December 1734, he was
one of those paid by the city government for making deliveries.

Claes Van Woert was last heard from in 1748 when he and Dirkje witnessed
a baptism in Albany.
